Quick Edit and Speed Print Capability for a Stand-Alone Ink Jet Printer

ABSTRACT

Printer ( 1 ) is provided with a mode to edit and print forms without reference to or interruption of a host computer and with immediate printing of one or more of the forms. Page data for the forms is preferably stored in flash memory ( 21 ) in a high level printer language. Preferably, at initiation of the forms mode at least the first listed document is immediately prepared by the control data processor ( 17 ) of the printer in bit mapped form for printing. Documents can be listed on the control panel by name for ready selection for printing.

CROSS-REFERENCE TO RELATED APPLICATIONS

This is a division of co-pending U.S. patent application Ser. No.09/858,694, filed May 16, 2001, which is a continuation-in-part ofco-pending U.S. patent application Ser. No. 09/610,129, filed 5 Jul.2000, both of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to printers. More particularly, thepresent invention relates to printers having document editingcapabilities.

2. General Background of the Invention

Lexmark currently makes a photoprinter, called the Photo Jetprinter5770, which allows stand-alone or computer attached printing. In thestand-alone mode, the 5770 photoprinter accepts CompactFlash andSmartmedia style memory cards and also supports attachment to anexternal ZIP drive. CompactFlash and Smartmedia are two popular stylesof memory cards used to store digital images produced by digitalcameras. The 5770 photoprinter can access and print pictures from allthree of the aforementioned media without requiring attachment to acomputer. This stand-alone printing capability distinguishes thephotoprinters from other types of personal printers.

There currently exist simple text-editing applications, which arecapable of opening a text file, editing the text in the file, and savingthe changed file. Examples of this are Microsoft's Notepad and WordPad.

There currently exist simple operating systems and file managementsystems, such as those used in Palm Pilot style devices, that arecapable of opening and editing text files without requiring a PC orlarge amounts of memory.

It is currently possible to interrupt Windows 95 with the parallel port,making it possible to ‘wake up’ the control program of a printer andstart other applications.

There currently exists the concept of Speed Dialing, in which a phonenumber is stored in memory on a telephone. The number can then berecalled by simply pressing one button, rather than having to dial theentire number.

There currently exist demonstration printers that are able to print outa picture when a potential customer pushes a button.

There currently exist laser printers that allow users to store documentsin the printer's memory (see U.S. Pat. No. 5,561,528, assigned to theassignee of the present invention). However, a PC is necessary in orderto edit the documents.

Many businesses purchase personal printers to generate custom formswhich are used in their daily operations. Examples of such forms mightinclude a bank's application for an automobile loan, a departmentstore's application for a store credit card, or a government office oragency's description of the types and prices of services offered by theoffice or agency. Prior to the invention of U.S. Pat. No. 5,561,528,businesses using printers to generate these custom forms are required toconnect a host computer such as a personal computer to the printer eachtime the form is generated.

The involvement of the host computer in the process of generating theform can vary from setup to setup. In the simplest of setups, the formdata is stored in the printer and the host is required to issue theappropriate commands to select a particular form and instruct theprinter to print the form. Other setups require that the form data bestored on the host. In this type of setup, the host must select a form,and send the form data to the printer; the printer does not distinguishthis type of printjob from other print jobs sent by the host.

In an existing, prior art printer sold by the assignee of thisapplication as the 4037 Page Printer, the printer has what is termed the“Retail” mode. In this mode the printer is placed in a state at whichthe printing of a single, predetermined document is the only printingfunction which is performed. The document constitutes a descriptivebrochure. Thus prospective customers in a retail sales environment canactivate the printing of only that form by an entry at the control panelof the printer stating “Press any key for one page demo”. Printing ofthe brochure takes a long time, since the brochure page is complex andeach printing of the brochure requires the final bit map to be preparedprior to printing. When in the Retail mode, the printer enters theRetail mode each subsequent time it is turned on. The Retail mode isactivated by the special entry of pressing and holding a predeterminedkey during turn-on. The same special entry of pressing and holding thepredetermined key during turn-on returns the printer to normal printingmode. When in the Retail mode the operator cannot access normal printerfunctions, such as select menu items on the panel or send print datafrom a host computer.

In an existing, prior art printer sold since early 1994 by the assigneeof this application as the 4039 plus laser printer, individual forms canbe printed, each after multiple entries to the control panel. At leastfour buttons entries on the control panel are pressed to display on thecontrol panel a list of forms (specifically, these entries are “Menu”,“Tests”, “More” and “Print Demo”). Then a print key is depressed toprint the selected form. The selected form is only then formatted to abit map. After it is printed, the control panel is returned to thenormal printing state and printing of the same or another form requiresthe multiple key entries and the formatting of the document printed.

The invention of U.S. Pat. No. 5,561,528 is operative in a system inwhich a page description is received in a high level printer language.Such printer language are discussed in some detail in U.S. Pat. No.5,222,200 to Callister et al, entitled Automatic Printer Data StreamLanguage Determination, and assigned to the assignee of this invention.

The invention of U.S. Pat. No. 5,561,528 employs the storing of forms inflash memory. Such an operation is a subject of U.S. Pat. No. 5,239,621to Brown III et al, entitled Printer With Flash Memory, and assigned tothe assignee of this invention.

BRIEF SUMMARY OF THE INVENTION

A stand-alone printer includes the ability to store, edit and print textfiles without the use of a PC or any type of removable storage media. Itdiffers from the current version of a stand-alone printer in thatdocuments are stored directly in the printer's memory and can be storedin either the document's original format or a printable format and canbe edited using controls on the printer.

The printer in accordance with this invention has non-volatile memory,preferably flash memory, for storing documents to be printed in theirhigh level language, which may be a page description language such asPostScript (trademark of Adobe Systems Incorporated) or an ASCIIbased-language such as PCL (trademark of Hewlett-Packard Co.), or agraphics language. The printer is controlled by standard electronic dataprocessing including a microprocessor and optionally combinationallogic, typically in an application specific integrated circuit, termedan ASIC. The electronic control has three modes, a normal mode in whichprinting is achieved by receiving data and printing it in normal orconventional fashion. The electronic control has a forms mode, selectedunder operator control or from incoming control signals, whichfacilitates printing of the stored documents. Such documents are storedin the non-volatile memory with data associated with them designatingthem as forms. As a part of the second mode, the forms are preferablyprepared upon initiation of the forms mode in bit map configuration bythe electronic control in the normal operation for the printer. As manyforms as permitted by available memory are so prepared. In such bit mapform they are ready for immediate printing. Preferably, they are alsostored in high speed memory of the control system, commonly known ascache memory, which typically is standard DRAM (dynamic random accessmemory). Each form is preferably associated with a unique name as partof the entering of data describing the form into the non-volatilememory. In the second mode the control system preferably displays theunique names of forms on an operator panel so that the forms can beselected. Upon selection of a form and its printing, preferably thecontrol system again displays and is prepared to immediately print atleast one form on the displayed list. Preferably the second mode has asubmode in which normal printing may be readily accessed from thecontrol panel and a submode in which normal printing is prevented, as itis with the previous Retail mode. In the third mode, the presentinvention takes the stand-alone printing capability of U.S. Pat. No.5,561,528 a step further by allowing editing, via the printer, ofdocuments stored in the section of nonvolatile memory of thephotoprinter.

The present invention bypasses the normal work involved in editing andprinting a text-style document (starting the computer, loading Windows,starting the correct application, opening the correct file, etc.) byallowing the printer to edit and print a frequently used file withoutthe direct use of a PC or removable storage media. This is done bygiving the printer the ability to store a frequently used file in theprinter's nonvolatile memory and edit the file based on user input,preferably via the Liquid Crystal Display (LCD) and control console.

This section of memory is preferably completely separate from the memoryused during regular printing operation and is preferably not altered orchanged in any way during the actual process of printing. Thus it is nowpossible to edit and print documents not only without a PC, but alsowithout the use of a removable storage media device such as CompactFlashor SmartMedia.

The present invention differs from demonstration printers that are ableto print out a picture when a potential customer pushes a button in thatit has an input console that allows the user to edit the document afterit has been stored in the printer's memory.

The present invention differs from existing laser printers that allowusers to store documents in the printer's memory in that a PC is notnecessary to access, edit and print the stored documents.

The present invention uses stand-alone printer technologies and adds theability to edit text documents (stored in the printer's nonvolatilememory) preferably via the LCD and user input console of the printer. Itis thus able to build off of the concepts of Speed Dialing andStand-Alone Printing to create a more self-sufficient stand-aloneprinter that is able to quickly access, edit and print a document bysimply pressing a few buttons, rather than having to load and print itfrom a PC or removable storage media. The basis for the presentinvention is to give the stand-alone photoprinter some type ofnonvolatile memory with in-printer editing capability, making itpossible to store frequently used files directly on the printer and editthose files using just the printer. The printer has the ability to edita file that is stored in the printer's memory based on user inputpreferably via the LCD and control console, and print the file if sodesired. The editing and printing functions can be performed withoutusing a separate computing device.

Two possible ways that files can be stored in the printer's nonvolatilememory are: the files are sent to the printer directly from thecomputer; or the files are read from a removable storage media device.When a file is copied to the printer's memory directly from thecomputer, the user has the choice of either keeping the file in itsoriginal format or in a ‘print format’. By keeping the file in itsoriginal format, it is still readable if it is copied from the printer'smemory back to the computer, or to a removable storage media device.However, the printer must convert the original format into a printableformat before being able to print the document. When the file is storedin ‘print format’, the printer is able to print the file with lessprocessing time being required. In the preferred implementation of thepresent invention, this ‘print format’ is a bitmap file.

The LCD provided by the stand-alone printer, for example, gives the userthe ability to interact and give commands to the printer. A menu optionis added to the currently available interface software to allow the userto select currently saved files in the printer's memory. The files canbe accessed using a file management system such as the one used on aPalm Pilot. By selecting a file, the user is given the option of editingthe fields of the document selected. Once the user has edited thedocument, he can either print the edited document or store the documentback into memory. The documents mentioned above can be of various types.Some examples are address labels, business cards income tax forms, orcommonly printed images.

For documents that are too large to be stored on the printer's memory,the user has the option of storing only the document's PC memorylocation on the printer. Thus, when the user chooses to ‘speed print’ afile for which this option has been chosen, the printer ‘wakes up’ theprinter's control program on the PC. The control program then finds andprints the correct file based on the memory location that the printergives it. When this option is chosen, the printer is no longer a‘stand-alone’ device as defined in the invention background section ofthis disclosure. However, because the printer performs all of thesoftware interaction, the user is still saved the time required to findand start the correct application, open the correct document, and chooseto print. It should also be noted that the user would not be able toedit documents for which this option has been chosen.

The present invention extends the functions of a stand-alone printer toinclude the ability to store, edit and print text files without the useof a PC or any type of removable storage media. It differs from thecurrent version of a stand-alone printer in that documents are storeddirectly in the printer's memory and can be stored in either thedocument's original format or a printable format and edited withoutusing a PC.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

For a further understanding of the nature, objects, and advantages ofthe present invention, reference should be made to the followingdetailed description, read in conjunction with the following drawings,wherein like reference numerals denote like elements and wherein:

FIG. 1 is illustrative of a printer in accordance with this invention;

FIG. 2 shows the control panel of the printer with the power switch off;

FIG. 3 shows the control panel of the printer with its initial displayat turn-on to the normal printing mode,

FIG. 4 shows the control panel of the printer with the display reachedby the control button opposite the word “Setup” as it appears in FIG. 3;

FIG. 5 shows the control panel of the printer with its display when inthe forms mode.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a printer 1 in accordance with this invention havingthe ability to edit and print forms on demand without significant delayat operator input without requiring involvement of a host computer. Ofcourse, few businesses currently operate in an environment where aprinter is not connected to some host computer. If anything, theopposite is true—multiple host computers are connected to one printer.However, when a printer 1 is in its mode for forms on demand, theoperator's host computer may operate independently of printer 1, forexample the host may process data associated with an application whichis different from the application associated with the custom forms ofthe operators' business. The operator edits and prints forms on printer1 without interrupting the host computer. Since printer 1 has thecapability of editing and printing the form independent of the hostcomputer, the operator can save a significant amount of time since theneed to exit or interrupt one application and start another is notrequired. This capability may be ideal, for example, for a loan officerwho has daily office responsibilities as well as responsibilities forinterviewing perspective loan applicants. When a loan applicant walks upto the officer's desk, the officer is no longer required to interrupt anapplication program currently in use to edit and print a loanapplication.

Page description information is received by printer 1 in a standardmanner from a communications cable 3. Printer 1 may be any suitableprinter with respect to normal imaging by composing bit images fromreceived data describing images in a language. For illustrative purposesprinter 1 is shown suggestive of an electrophotographic printer havingan optical system 5 operative on drum 7. Drum 7 transfers images definedby optical system 5 at transfer station 9 to paper 11. The image isfixed, typically by heat, at fixing station 13, and the finished printerpage is delivered to output tray 15. Printer 1 could instead be, forexample, an inkjet photoprinter.

Data processor 17 in printer 1 controls operation of printer 1.Typically, data processor 17 is a microprocessor, often with one or moreASIC combinational logic circuits to speed certain operations. As partof this operation, information received on cable 3 in a high levellanguage is interpreted by data processor 17 to create a bit map of thepage to be printed. For example, printer languages typically describecharacters of the alphabet in an ASCII code. The form of the characteris stored in fonts and these fonts are used to define the final bit map.Other information may be in the form of vectors. Interpretation of suchhigh level languages is now entirely standard and will not be elaboratedon further as its use in this invention is straightforward. The 4037Page Printer sold commercially by the assignee of this inventionrepresents a printer which this invention may employ in its existingform except for the forms on demand and editing elements as described.

Information received on cable 3, as well as other information, is storedin volatile memory 19, a standard DRAM, or non-volatile memory 21, underthe control of data processor 17. Memory 21 is preferably flash memoryas that provides size and functionality equivalent to the standardvolatile memory, such as DRAM, at acceptable cost. A third memory 23represents standard NVRAM (non-volatile random access memory). NVRAM isexpensive and relatively slow, and its use is limited accordingly. It isused primarily to store status and control information, includinginformation defining the mode of the printer 1 in accordance with thisinvention.

Printer 1 has a control panel 25 with a middle display 27 and an off-onpower switch 29. FIG. 2 shows the display 27 as it appears prior to turnon by switch 29. The display is blank. It has four buttons on the rightfrom the top, 40, 42, 44, and 46. System control by data processor 17responds to the following to enter the forms on demand mode permittingoperator intervention (i.e., not the Retail mode): 1) Key 44, the thirdkey from the top is depressed and held by an operator of printer 1. 2)While key 44 is depressed, switch 29 is turned to the power on position.Once in this mode, the operator may simply press ready key 48 for dataprocessor 17 to return to normal printing mode (other controls, such asa reset entry, are also operative). Absent depressing of key 48 or otheroverride entry, printer 1 is in the forms on demand mode described morefully below.

Another entry to this form mode is from the control panel 25. Systemcontrol by data processor 17 responds to the following:

-   -   1) Printer 1 is turned on by switch 29. (Printer 1 enters normal        printing mode when that was the mode at the immediately previous        turn off by switch 29. If the power-on default is not normal        printing, this entry is not applicable until printer 1 is        brought to normal printing mode.)

2) Display 27 then has the term “SETUP” next to key 40 as shown in FIG.3. Key 40 is depressed.

-   -   3) Display 27 then has the term “FORMS” next to key 46, as shown        in FIG. 4. Key 46 is depressed. Printer 1 enters the forms mode.

Only when the forms on demand mode is entered by the key 44 at turn-on,NVRAM 23 stores data designating that as the power-on default, to whichdata processor responds at subsequent turn-on. This is reversed by onceagain depressing key 44 while turning on switch 29, at which time datain NVRAM is changed to that responded to by data processor 17 to bringprinter 1 at turn-on to the normal printing mode.

FIG. 5 shows the display 27 after entry in the forms mode in which morethan four forms are stored as forms in non-volatile memory 21 of printer1. The names of three forms are displayed next to buttons 40, 42 and 44respectively. The term “MORE” appears next to button 46, which indicatesthat further forms will be displayed by pressing of button 44. Uponentry of the forms mode, either by turn-on with switch 29 or fromcontrol panel 25 as just described, printer 1 under control of dataprocessor 17 preferably immediately effects normal bit mapping of theform in non-volatile memory 21 to appear first (next to key 40) ondisplay 27. That bit mapped data is stored in DRAM 19. The other formsin the order they appear on display 27 are preferably similarly bitmapped and stored as the available space in memory 19 permits.

To edit and print one of the forms, for example the “EMPLOYEE FORM”indicated in FIG. 5, button 42, the button next to that form, is pressedby the operator. The latest version of the PhotoPrinter from Lexmark isthe Kodak PPM200. The PPM200 contains a color LCD and a control panelthat allows the user to view images contained in detachable memory (i.e.Compact Flash or Smart Media cards). The PPM200 also has a USB Hostport, which allows the user to attach an Iomega Zip Drive to the printerand view the images contained within. Currently the PPM200 allows theuser to select text characters using the control panel. Once selectedthese characters can be overlayed onto the image as a template. The sameimage viewing technology could be used in the present invention to zoomin on certain areas of the image. The same character selectiontechnology could be used in the present invention to take the user'sinput and alter the selected portion of the image directly in the bitmapof the image. Once altered this image could be stored for futureprinting. Note that this would be limited to images in their originalformat. Images that have already been converted to print data would notbe able to be altered using this current technology.

Printer 1 under control of data processor 17 prints the edited form innormal fashion while the word “BUSY” is caused to appear on display 27.In this mode operator intervention to interrupt printing is available tothe operator to the same extent as in normal printing.

With the printer of the present invention, one need not always editstored documents before they are printed; at times a stored documentwill be printed without editing. In such a case, the printer of thepresent invention can operate as does the printer of U.S. Pat. No.5,561,528.

The employee form may not be in readily accessible memory 19 (“cache”being a term for memory which is readily accessible to its associateddata processor) because memory 19 could not store it after storing thefirst form on the list of display 27, bank statement. In this eventprinting is delayed while data processor 17 prepares the employee formin a bit map as required for printing. In the forms mode one preferredalternative stores the complete new form being printed; in theillustration the employee form is then stored in cache memory 19. Thisis a recognition that the printing of one copy suggests that the sameform is the most probable form to be printed the next time a form isprinted. Thus, if the next key after printing employee form is again key42 to call for a second employee form, printing will begin immediatelyfrom the bit mapped data in cache memory 19. A second preferredalternative reformats the first form on the display 27 immediately afterprinting whichever form is printed. This is a recognition that theoperator may wish to know with certainty which form can be immediatelyprinted, as when the printer has multiple operators.

The “Retail” submode of the forms mode is not entered from the controlpanel 25 in this preferred embodiment. It is only entered bypredetermined code entered in non-volatile memory 21. This is by specialentry at the host computer. Data processor 17 recognizes that code atturn-on and responds by bringing printer 1 to the Retail mode.

Once in the Retail mode, it can be exited to the normal printing mode bythe following:

-   -   1) Key 42 is depressed and held.    -   2) While key 42 is depressed, switch 29 is turned to the power        on position

Until exit of the Retail mode, at each turn-on data processor 17 bringsprinter 1 to the Retail mode by reference to default data stored innon-volatile memory 21.

Except that it can only be entered by coding in the non-volatile memory21, the Retail mode as just described does not differ from that of theprior printer mentioned under the heading “Background of the Invention.”In accordance with this invention, the bit map of forms is madeimmediately on entering the Retail mode and stored in cache memory 19 asdescribed for the forms on demand mode. Additionally, in the Retail modethe content of display 27 may be changed from “Press any key for onepage demo”, to a list of brochures like the list of forms in the formson demand mode.

The preparation of forms and brochures may be done by a number ofapplication programs. The forms are typically prepared from a blankcondition by an operator creating a wholly or largely unique form usinga personal computer. Alternatively, the form may be scanned from a copy.In any event, the form, typically in a high level language as previouslymentioned, comes to exist and may be transmitted to printer 1 by signalson cable 3. Such transfer, as will be described immediately following,is conventional and forms no part of this invention. A special softwareutility for the host computer may be provided to facilitate transfer.Printer 1 under control of data processor 17 responds to the followingcommands to enter forms into non-volatile memory 21:

-   -   1) Switch 29 is turned on and printer 1 is brought to the normal        printing status.    -   2) Conventional driver software suitable to printer 1 basic        operation is employed at a host computer applying the signals to        cable 3.    -   3) A unique command for storing files is sent on cable 3.    -   4) A unique command for opening and naming a file containing a        form is sent, the name being that which will appear on display        27.    -   5) With the form prepared by an application program, the “print        to file” entry is made to the application program. The user then        instructs the application to print the document in the normal        manner. The print to file designation causes the application to        create the form on the hard disk on the host computer. Once this        operation is complete, the user exits the application and sends        the file to the printer.    -   6) A unique command is sent to close the file.    -   7) A unique command is sent to designate storage of the form in        non-volatile memory 21 as a form. Step 4 has designed the data        so stored as a form with the name assigned.

The foregoing procedure is repeated for each form to be stored innon-volatile memory 21. Once the forms are so stored, they may be editedusing the printer as mentioned above.

Final printing from the bit map preferably is modified by knowntechniques to remove stair step appearance of slanted lines, known asenhancement of resolution, by adjustment made based on the final bitmap. Alternatives will be apparent and may be devised within the spiritand scope of this invention.

For documents that are too large to be stored on the memory of printer1, the user has the option of storing only the document's PC memorylocation on the printer. Thus, when the user chooses to ‘speed print’ afile for which this option has been chosen, the printer 1 ‘wakes up’ theprinter's control program on the PC. The control program then finds andprints the correct file based on the memory location that the printer 1gives it. When this option is chosen, the printer 1 is no longer a‘stand-alone’ device as defined in the invention background section ofthis disclosure. However, because the printer 1 performs all of thesoftware interaction, the user is still saved from the time required tofind and start the correct application, open the correct document, andchoose to print. It should also be noted that the user would not be ableto edit documents for which this option has been chosen.
